Application nle. January it, 191e. Eteral No. 209,947.

oi Ohio, have invented certain new and `seitul llinprovenients in Bird-Traps,` ot' i which the lfollowing a specilication.

rlllhis invention relates to i,inprovenientsin traps, and` particularly to types eniployed in catching birds, small animals and the like, and has its special object the provision ot means whereby upon the entry ot a live object the inlet is instantai'ieously closed hy a gate, coniining the entered hird or animal therevvithin.

Another object is to provide means Where hy the gate is secured when in a closed po eition so that it cannot he' opened troni the interior.

ylhese and other like objects are attained hy the novel construction and combination olf' parts hereinafter described and shown in 'the `accornpanying drawings, 'forming a n1aterial part ot this specilication and in whichllligure l is a vertical sectional view taken on line 1.-1 ot lig. 3 and showing an einhodiment ot the invention.` p

IiP-ig. 2 is a perspective 'view ot the trw'o'er tera and inovahle platiiorrn used in the constrnction. i

llig. 3 .is a horizontal sectional view taken on line 8 3 ot llig. l.

llig. i is a tragniental perspective "view ind ioating the gate locking means, and lig. 5 is a perspective View oit the trigger engaging means.

rllhe invention comprises a hollow rectangulaitranie, mounted at the bottoni upon supports l0, from which rise rigid corner uprights ll and l2, respectively at the rear and lf'ront, which are engaged with the top and hottoin respectively lll, and l5, and a rear plate i6, While between the corner elenionts ll and 12, on the sides are 'transparent plates 18, Yfor the provision ot light.

llhe trent uprights l2 are grooved to reccive a sliding gate lil :treely niovahle vertically therein and to which are attached cinds E30, running over rollers 2l, supported hy brackets 2Q; and secured to the `cover lil.

'lhe opposite ends of the cords 2() are en* gaged with a har 24:, at the center' oit which is attached another cord 25,passing over a pulley 27, rotatable in a bracket-28, fastened to the rear Wall 16, ot the structure, the cord passing helene another pulley 30, rotatahlein a hil'aclret 3l, afin-:ed to the hottoin plate l5 and then through a passageBQ, inthe hlo lr 3B also seeurerfl to the bottoni plate l5, Where a knot 35, is termed, the extending end of the cord heing securedto a loose stop 3G to prevent complete Withdrawal ot the cord through the passage 32.

'.lrigger 3&3 has secured to it hy the rivets 39, a spring 410, the tree end ot which is adapted to engage in a recess 42, termed across the hloclr 33 at the end ot the passage 32, the extreme outer edge ot the spring `iin-tiring contact with the knot 35', so as to prevent the lrnot troni heilig passed through the passage when the trap is in a set or ope 'ative condition. A pair of spring arms lllare :tornied with the spring 4:0, which. are adapted to engage with a haitior lure 48, so as to hold the saine securely near the end ot the 'trigger 38.

lt will loe ohvious upon touching the hait or lure, the spring fr0, will he displaced troni the recess 4t2, allowing the knot 35 to pass through the passage 32, and permit the gate 18 to drop, harring the entrance to Athe structure. '.lhis action is accelerated hy means oit a cord l5 secured to the lower part ot the gate and which is passed around. a. pulley a6, in the supports 10, and con nected with a spirally Wound tension spring a9, secured at one end by the pin 50, set in the hottoin plate or lloor 'lho upper edge 52, olf the gate 19 is beveled to engage with the hook 53, secured in the hinge 5a., arranged on the upper sur- Ytace of the top plate 141-., the hoolr having upon it a projection hy means olf which it may he readily manipulated and opposite the projection 55, is an eye 5G, engaged with a cord 5d, the 'tree end oit which is attached to one oit the cords Q0 :in such manner to prevent entanglement.

lfn operation the gato is raised, the spring d0 extended, and the trigger 3S is placed so as to 1n alte contact with the upper surface ol the door l 5 and the outer surface of the hloclr 33 at tpl-reir junction, the knot 85 heing drawn through. the passa 82, engaged hy the edge ot the spring lll and held until such time as the trigger iti is disturhed, hy inalring contact with the lure a3, causing the trigger to heeoine loosened permitting the gate to de scend inclosing wh atever object may he Withl10W structure having an entrance and a sliding gate adapted to close the entrance.

of a cord adapted to hold said gate in a raised position, a block through which said cord passes, a trigger engageable Within said structure against said block, a spring element secured to said trigger, adapted to engage withV said cord, means for securing a lure to said trigger, and a spring adapted to close said gate upon the dislocation lof said Y trigger.

2. In a trap, the combination with a hol- 10W structure, having an entrance and a sliding gate adapted to close the entrance, of a pair of cords attached to said gate, said cords being extended within, close to the upper portion of the structure, a bar connected with said cords, another cord engaging centrally with said bar7 and passingI through the lower portion of' said structure, a block arranged upon the bottoni oi said structure having an opening through which said cord passes, means for engagingr said cord Within said opening, means permitting the disengagement of said engaging means`r said means being operated by a hire, a spring for accelerating the movement of said gate, and means for locking lsaid gate when in a lowered position thereby prevent'- ing it from being raised from the interior.

In testimony whereof I have allixed .my
